obair-lann air fhàs daoimeanan gia le teisteanas Carat cuideam
Is e aonad cuideam obair-lann daoimeanan a dh’ fhàs carat (ct), 1 carat = 100 puingean = 0.2 gram
Nuair a tha iomraidhean 4C eile coltach, mar as motha cuideam an daoimean, is ann as àirde an luach
Chan eil an clàr seo air a chleachdadh ach mar iomradh airson coimeas a dhèanamh eadar diofar mheudan carat, a dh’ fhaodadh a bhith eadar-dhealaichte bhon fhìor mheud.
